Evaluation of Seed Dressing Pesticides on Barely Shoot Fly, Delia flavibasis and Barely Stripe, Pyrenophora graminea Disease in South-Eastern Ethiopia

During meher season, 2013 and 2014, the efficacy of two seed dressing pesticides Apron Star 42 WS and Joint TM 246 FS, possessing fungicidal and insecticidal characteristics were evaluated against plant disease (barley stripe) and insect pest (barley shootfly) in two rates and 11 locations, 8 in Arsi and West Arsi zones, and 3 in Bale zone, in South-eastern Ethiopia. Pooled zone average data revealed that Apron Star 42 WS and Joint TM 246 FS with higher rates, 250g and 200m/100kgseed, respectively, give a better control of barley shootfly under Bale zone circumstances where this pest is most prevalent and severe. The lower rates of Apron Star 42 WS (125g/100kgseed) and Joint TM 246 FS (100ml/100kgseed) did not significantly differ from their higher rates in barley stripe management in all zones and shootfly in Arsi and West Arsi zones, and thus, both higher and lower rates of both seed treatment pesticides are recommended to be used as one of the components of barley diseases management options in malt barley and food barley production in South-eastern Ethiopia.
